Resistance of 2 S. aureus strains (laboratory strain 209 and antibiotic-resistant strain 603 isolated from a patient) to decamethoxin (I) developed more slowly than to streptomycin, penicillin, neomycin, or levomycetin during 10 passages through meat-peptone broth with these preparations There was no cross resistance between decamethoxin and these antibiotics. Variants resistant to I showed a lower pathogenicity and sharply inhibited dehydrogenase activity. The antibiotic-resistant variants of each strain had the same or higher pathogenicity than the initial strain.

Miao, Qingqing published the artcileNear-Infrared Fluorescent Molecular Probe for Sensitive Imaging of Keloid, Safety of 2-Chlorotrityl chloride, the publication is Angewandte Chemie, International Edition (2018), 57(5), 1256-1260, database is CAplus and MEDLINE.

Early detection of skin diseases is imperative for their effective treatment. However, fluorescence mol. probes that allow this are rare. The first activatable near-IR (NIR) fluorescent mol. probe is reported for sensitive imaging of keloid cells, skin cells from abnormal scar fibrous lesions. As keloid cells have high expression levels of fibroblast activation protein-alpha (FAPα), the probe (FNP1) is designed to have a caged NIR dye and a FAPα-cleavable peptide substrate linked by a self-immolative segment. FNP1 can quickly and specifically turn on its fluorescence at 710 nm by 45-fold in the presence of FAPα, allowing it to effectively recognize keloid cells from normal skin cells. Integration of FNP1 with a simple microneedle-assisted topical application enables sensitive detection of keloid cells in metabolically-active human skin tissue with a theor. limit of detection down to 20 000 cells.

Herein, a first achievement in 1,1-difunctionalization of alkenes RCH=CH₂ (R = hexyl, cyclohexyl, 3-(1H-pyrrol-1-yl)propyl, 9H-carbazol-9-ylmethyl, etc.) with aryl chlorides ArCl (Ar = Ph, 2,4-difluorophenyl, 1-[(tert-butoxy)(oxo)methane]-1H-indol-6-yl, 2H-1,3-benzodioxol-5-yl, etc.) as coupling partners was reported. The success is predominantly ascribed to the judicious selection of 1,2-diamine ligand. This study provides an efficient protocol for the synthesis of secondary benzyl boronates RCH₂CH(R¹)Ar (R¹ = tetramethyl-1,3,2-dioxaborolan-2-yl) from easily accessible feedstock chems. Furthermore, the distinguished features of this method include excellent 1,1-regio- and chemoselectivity, good functional group tolerance and easily-operational catalytic reaction conditions.

Wu, Shaotong published the artcileA stereo configuration-activity study of 3-iodo-4-(2-methylcyclohexyloxy)-6-phenethylpyridin-2(2H)-ones as potency inhibitors of HIV-1 variants, HPLC of Formula: 21286-54-4, the publication is Organic & Biomolecular Chemistry (2016), 14(4), 1413-1420, database is CAplus and MEDLINE.

3-Iodo-4-(2′-methylcyclohexyloxy)-6-phenethylpyridin-2(1H)-ones, as effective non-nucleoside reverse transcriptase inhibitors, were synthesized and resolved with different configurations. Biol. results revealed that the trans-racemate exhibited more potent activity than the cis-isomers. Noticeably, the trans-(S,S)-enantiomer turned out to be significantly more potent than its counterpart enantiomer against wild-type and double-mutant strains with high selectivity indexes.

Kornecook, Thomas J. published the artcilePharmacologic characterization of AMG8379, a potent and selective small molecule sulfonamide antagonist of the voltage-gated sodium channel NaV1.7, HPLC of Formula: 929626-16-4, the publication is Journal of Pharmacology and Experimental Therapeutics (2017), 362(1), 146-160, database is CAplus and MEDLINE.

Potent and selective antagonists of the voltage-gated sodium channel NaV1.7 represent a promising avenue for the development of new chronic pain therapies. We generated a small mol. atropisomer quinolone sulfonamide antagonist AMG8379 and a less active enantiomer AMG8380. Here we show that AMG8379 potently blocks human NaV1.7 channels with an IC50 of 8.5 nM and endogenous tetrodotoxin (TTX)-sensitive sodium channels in dorsal root ganglion (DRG) neurons with an IC50 of 3.1 nM in whole-cell patch clamp electrophysiol. assays using a voltage protocol that interrogates channels in a partially inactivated state. AMG8379 was 100- to 1000-fold selective over other NaV family members, including NaV1.4 expressed in muscle and NaV1.5 expressed in the heart, as well as TTX-resistant NaV channels in DRG neurons. Using an ex vivo mouse skin-nerve preparation, AMG8379 blocked mech. induced action potential firing in C-fibers in both a time-dependent and dose-dependent manner. AMG8379 similarly reduced the frequency of thermally induced C-fiber spiking, whereas AMG8380 affected neither mech. nor thermal responses. In vivo target engagement of AMG8379 in mice was evaluated in multiple NaV1.7-dependent behavioral endpoints. AMG8379 dose-dependently inhibited intradermal histamine-induced scratching and intraplantar capsaicin-induced licking, and reversed UVB radiation skin burn-induced thermal hyperalgesia; notably, behavioral effects were not observed with AMG8380 at similar plasma exposure levels. AMG8379 is a potent and selective NaV1.7 inhibitor that blocks sodium current in heterologous cells as well as DRG neurons, inhibits action potential firing in peripheral nerve fibers, and exhibits pharmacodynamic effects in translatable models of both itch and pain.

Stevenson, Graeme I. published the artcileSolid-phase synthesis of Biotin-S-Farnesyl-L-Cysteine, a surrogate substrate for isoprenylcysteine Carboxylmethyltransferase (ICMT), SDS of cas: 42074-68-0, the publication is Bioorganic & Medicinal Chemistry Letters (2013), 23(20), 5671-5673, database is CAplus and MEDLINE.

Inhibition of isoprenylcysteine carboxylmethyltransferase (ICMT) is of particular interest as a potential target for the development of cancer chemotherapeutic agents. Screening for inhibitors of ICMT utilizes a scintillation proximity assay (SPA) in which biotin-S-farnesyl-L-cysteine (BFC) acts as a surrogate substrate. A solid-phase synthesis protocol for the preparation of BFC using 2-chlorotrityl chloride resin as a solid support has been developed to provide sufficient supply of BFC for high throughput screening (HTS) and subsequent chem. campaigns to target inhibitors of ICMT. The BFC prepared by this method can be produced quickly on large scale and is stable when stored at -20° as a solid, in solution, or on the resin.
